As you have seen, both of those cameras posses the exact same sensor measurements but not the same megapixels. You should anticipate the Pentax S1 to render greater detail due to its extra 4MP. Greater resolution can also allow you to crop images somewhat more aggressively. The fresher S1 will have an edge when it comes to sensor innovation.
